CHARBONE Secures Long-Term Hydrogen Supply Contract with Hone Inc. to Support Clean Energy Solutions for the Entertainment Industry

Varennes, Quebec, June 10, 2026 – CHARBONE CORPORATION (TSXV: CH; OTCQB: CHHYF; FSE: K47) (“CHARBONE” or the “Company”), a vertically integrated industrial gases company focused on production, distribution and storage of clean ultra-high purity (“UHP”) hydrogen and other strategic industrial gases, is pleased to announce that it has entered into a long-term hydrogen supply contract with Hone Inc. (“Hone”), a provider of mobile hydrogen power solutions for a variety of applications, including the film and television production industry.

Deepening a Proven Commercial Relationship

This agreement follows CHARBONE’s January 22, 2026 announcement of its first hydrogen sales in Ontario to Hone. The long-term supply contract with Hone formalizes and extends that commercial relationship, reflecting the growing acceptance of CHARBONE’s clean hydrogen as a proven energy solution for on-set power generation in one of North America’s most active production markets.

Hone delivers mobile hydrogen power as a clean alternative to diesel generators for film and television productions. Hone’s trailer-mounted 165 kW hydrogen ICE generator systems replicate the standard production 1,400-amp diesel genset that eliminates emissions on-set. Each generator day can displace more than 1.5 tonnes of CO₂ compared to diesel operations. CHARBONE’s hydrogen serves as the fuel source for Hone’s proprietary Fuel Block™ delivery and drop-and-swap refueling system, which enables uninterrupted power throughout production.

Growing Acceptance in the Entertainment Sector

The commercial traction achieved through this partnership demonstrates the real-world viability of hydrogen as a clean, reliable power source in mobile and time-sensitive production environments. A major Hollywood Studio with multiple productions filming in Toronto has utilized Hone’s hydrogen generator service and CHARBONE’s clean hydrogen on several occasions, an important validation of both the technology and the supply chain supporting it.

Contract Terms

The long-term supply agreement is binding in nature and covers a term of two years, subject to the terms and conditions agreed upon by both parties.

Consistent with its established practice, CHARBONE is not disclosing the volume, pricing, or financial terms of this commercial arrangement in order to maintain its competitive position in the market. The Company has noted that demand for its clean UHP hydrogen continues to outpace the available supply, a market dynamic that underscores the strategic importance of expanding CHARBONE’s production network. Revenues generated by the Company’s production, distribution, and service activities are presented on a consolidated basis in its quarterly financial statements.

Management Commentary

“This long-term supply agreement with Hone is a direct extension of the commercial momentum we established earlier this year, and it reflects something meaningful: the entertainment industry is not just testing hydrogen, it is integrating it into active studio production workflows,” said Dave Gagnon, Chairman & Chief Executive Officer of CHARBONE. “Clean hydrogen is proving its value in some of the most demanding operational environments, where reliability, safety, and performance are non-negotiable. We are proud to be the supply partner enabling that transition, and we look forward to supporting Hone and their clients across what we expect to be a growing number of Hollywood productions.”

“Partnering with CHARBONE on a long-term basis gives Hone the supply certainty we need to confidently serve our clients across multiple Hollywood productions, and a diverse range of other industries and clients” said Ry Smith , CEO of Hone. “Clean, reliable hydrogen is the foundation of our service offering, and CHARBONE’s clean UHP hydrogen meets the quality and logistics standards our customers depend on.”

PRESS RELEASE

CHARBONE Announces Change of Corporate Name and Registered Address

Brossard, Quebec, June 3, 2026 – CHARBONE CORPORATION (TSXV: CH; OTCQB: CHHYF; FSE: K47) (“CHARBONE” or the “Company”), a vertically integrated industrial gases company focused on production, distribution and storage of clean ultra-high purity (“UHP”) hydrogen and other strategic industrial gases, is pleased to announce the official change of its corporate name from Charbone Hydrogen Corporation to Charbone Corporation, and strategic relocation to Varennes, Quebec.

Name Change

Following shareholder approval received at the Company’s annual general and special meeting held on March 28, 2025, Charbone decided to execute the official name change to “Charbone Corporation” to better reflect the Company’s evolution beyond its foundation as a hydrogen producer into a fully integrated industrial gases platform.

The Company’s expanded platform addresses multiple molecules including hydrogen, oxygen, helium, and other specialty gases, serving high-growth end markets such as semiconductors, AI/data centers, advanced pharmaceuticals, and aerospace and defense.

The name “Charbone Corporation” better captures the breadth of this platform and positions the Company alongside established industrial gases leaders as it continues to scale its network of regional supply hubs across North America and internationally.

The articles of amendment effecting the name change have been filed pursuant to the Business Corporations Act (Quebec) and are available on the Company’s SEDAR+ profile at www.sedarplus.ca. The name change has been approved by the TSX Venture Exchange (“TSXV”). The Company’s ticker symbols on the TSXV (CH), OTCQB (CHHYF), and Frankfurt Stock Exchange (K47) remain unchanged. No action is required by existing shareholders, and no certificates representing common shares need to be exchanged. Under the name change, effective on June 8, 2026, the CUSIP number assigned to the common shares will be 159916105 (ISIN: CA1599161058).

Change of Registered Address

In connection with its ongoing operational ramp-up, CHARBONE has also relocated its registered and principal business address to 1645 boulevard Lionel-Boulet, Suite 304, Varennes, Quebec, J3X 1P7.

PRESS RELEASE

CHARBONE and Vema Hydrogen Build Québec Hydrogen Supply Chain to Meet Wellhead-to-Industrial Gas Demand and Reduce Transport Costs

New agreement anchors a scalable hydrogen supply chain in one of North America’s fastest-growing energy hubs

Brossard, Quebec, May 19, 2026 – CHARBONE CORPORATION (TSXV: CH; OTCQB: CHHYF; FSE: K47) (“CHARBONE” or the “Company”), a vertically integrated industrial gases company focused on production, distribution and storage of clean ultra-high purity (“UHP”) hydrogen and other strategic industrial gases, today announced a Conditional Offtake and Infrastructure Development Agreement (“Agreement”) with Vema Hydrogen (“Vema”) to develop a new hydrogen production and processing project in Québec. The site adds a valuable new resource for the region’s merchant industrial gas customers and strengthens the broader supply chain. The Agreement pairs Vema’s Engineered Mineral Hydrogen (“EMH”) production with CHARBONE’s purification, compression, and distribution capabilities to serve growing demand from CHARBONE’s industrial merchant hydrogen customer base up to 15 tons per day.

Leveraging Québec’s position as a regional hydrogen hub, the partnership sets the framework for a “well-to-market” supply chain in the region. The province’s concentrated industrial demand and proximity to key transportation networks minimize long-distance fuel transport and reduce overall system costs, making it a highly efficient geography for hydrogen production and distribution. The project’s design allows Vema to expand into emerging markets including low-carbon maritime and aviation fuel manufacturing, e-fuels, and power generation, where CHARBONE’s purification and distribution capabilities could integrate into multiple parts of the value chain.

“The market is demanding high-value industrial gases and our customers need cleaner, more reliable supply. By pairing Vema’s EMH feedstock with our purification and distribution capabilities, we’re strengthening Québec’s position as a regional hub for next-generation hydrogen,” said Dave Gagnon, President and CEO of CHARBONE.

On the heels of completing drilling and initiating pilot operations in Québec by Vema, the Agreement represents the latest milestone in Vema’s accelerating commercial progress. It broadens the Company’s offtake pipeline into industrial gas distribution, e-fuels, and clean mobility as Vema positions its technology for initial market deployment.

“Across high-value markets – from aviation and maritime fuels to industrial gases, there is incredible demand for Vema’s low-carbon Engineered Mineral Hydrogen. Now, more than ever, we need a pathway to deliver these low-carbon fuels,” said Pierre Levin, CEO of Vema. “As a valued offtaker and partner, CHARBONE’s established logistics networks provide the infrastructure and pathway to meet the immediate market demand for industrial customers across North America.”

PRESS RELEASE

CHARBONE Releases Updated Presentation and Fact Sheet

Updated investor materials highlight the industrial gas market tailwinds and an expanding portfolio of clean UHP hydrogen production plants and regional supply hubs

Brossard, Quebec, May 13, 2026 – CHARBONE CORPORATION (TSXV: CH; OTCQB: CHHYF; FSE: K47) (“CHARBONE” or the “Company”), a vertically integrated industrial gases company focused on production, distribution and storage of clean ultra-high purity (“UHP”) hydrogen and other strategic industrial gases, today announced the release of its updated Corporate Presentation and Fact Sheet, now available in the Investors section of the Company’s website at www.charbone.com.

The updated materials provide investors and stakeholders with a refreshed view of CHARBONE’s vertically integrated industrial gases platform, the structural growth dynamics shaping the global UHP gas market, and the Company’s growing portfolio of clean UHP hydrogen production plants across Canada, the United States, and Asia-Pacific.

A Growing, Structurally Undersupplied UHP Industrial Gas Market

CHARBONE operates in a critical segment of the modern industrial economy. The updated investor materials highlight the favorable market backdrop supporting the Company’s growth strategy, with demand drivers anchored in semiconductor fabrication, AI and data centers, advanced pharmaceuticals and biotech, aerospace and defense, and precision laboratories.

Global Ultra-High Purity (UHP) Gas Market

Clean UHP Hydrogen – CHARBONE’s Core Production Molecule

UHP Helium – Strategic, High-Margin and Supply-Constrained

UHP Semiconductor Gas Segment

Clean UHP Hydrogen Production Project Pipeline

The updated Corporate Presentation provides additional clarity on CHARBONE’s project pipeline. The Company’s modular, demand-driven approach is designed to deploy up to 16 hydrogen projects in proximity to end-users, at a fraction of the capital intensity of traditional centralized mega-plants. Each project is designed with up to 5 phases of production capacity, each deployed within 6-12 months in line with local demand and access to local renewable energy.

Sorel-Tracy, Quebec, Canada – Flagship Project (Commercial Production)

Detroit, Michigan, United States

Wisconsin, United States

Malaysia, Asia-Pacific

Additional Pipeline

Beyond the four projects above, the Company is evaluating 12+ additional plant opportunities across North America and Asia-Pacific, with a longer-term vision to expand the platform across the broader basket of industrial gases.

Regional Supply Hubs Reinforce Recurring Revenue

CHARBONE’s hydrogen production assets are supported by a network of CHARBONE’s Regional Supply Hubs for the storage and distribution of industrial gases. The Company is developing hubs in Ontario, Quebec, Nova Scotia and New York, with a target of 6-8 hubs total across North America. Hydrogen and helium tube trailers have been deployed, supporting commercial deliveries across Ontario, Quebec and New York State, and multi-year supply agreements are in place with a subsidiary of one of the world’s largest chemical and industrial conglomerates, providing CHARBONE with a recurring revenue foundation.

Management Commentary

“The updated Corporate Presentation and Fact Sheet bring together, in one place, the market context and the project execution story that we believe make CHARBONE a differentiated investment opportunity. The structural undersupply of clean UHP hydrogen and helium, combined with accelerating demand from semiconductors, AI, data centers, advanced pharma, and aerospace, defines a multi-decade tailwind, and our modular, decentralized model is purpose-built to capture it. With Sorel-Tracy in commercial production, Detroit and Wisconsin advancing, and Malaysia entering an equity-participation phase, our pipeline has never been clearer or more tangible,” said Dave B. Gagnon, Chairman and Chief Executive Officer of CHARBONE.
